Our AM16/32B multiplexer now has removable terminal strips, allowing the wiring to remain intact while the multiplexer is used elsewhere. The green terminal strips are easily removed; no tools are required. Another change to the AM16/32B is that it no longer comes with its aluminum terminal cover since most users do not need it. However, the terminal cover (pn 19237) as well as replacement terminal strips may be purchased separately from Campbell Scientific (see AM16/32B Ordering Info).
